Dumbbell-shaped specimens were made from diaphysis of rat femur. After the specimens were immersed in 32, 37, and 42℃ saline solution for 2 and 4 weeks, tensile tests were performed. There were no significant differences in the effects of temperature on the mechanical properties of the specimens immersed for 2 weeks. Tensile strength of the specimens immersed in 37 and 42℃ saline solution for 4 weeks was significantly smaller than that in 32℃. These results indicate that long-term exposure to high temperature induces the decrease in the mechanical strength of femur.
